MBCN AutoMax ControlNet Module

Overview

This chapter contains the following information:

• module overview

• a summary of hardware features

• a description of how the hardware works

Module Overview

The MBCN module makes it possible for an application running in an

AutoMax Controller to communicate with and control ControlNet I/O

devices. The MBCN can also exchange data with other processors over

the ControlNet network using scheduled produced and consumed data.

The MBCN uses the standard AutoMax memory-mapped interface to the

host processor.

All I/O data is mapped into AutoMax registers 16384-32767. You can

select the register assignment for the data for each connection or have the

configuration.

The module:

• supports up to 127 scheduled connections, up to 480 words per

connection

• supports a maximum of 16 Kbytes total input data

• maps input data into AutoMax Processor registers 16384-24575

• supports a maximum of 16 Kbytes total output data

• maps output data into AutoMax Processor registers 24576-32767

• provides global status on all originator to target (O=>T) connections

and global status on all target to originator (T=>O) connections

• provides status on each connection, in AutoMax registers 15362-

15614, two 16-bit words per connection. You map the location of the

status information for a connection using RSNetWorx. This requires

major revision 2 of the MBCN firmware and RSNetWorx for

ControlNet 4.11 or later. Major revision 1 of the MBCN firmware

does not support status on individual connections

You use RSNetWorx for ControlNet to configure the I/O devices being

scanned and all scheduled produced and consumed connections.

The MBCN maintains standard ControlNet diagnostic counters, as well

as additional diagnostic counters, to monitor MBCN operation and to

diagnose problems.

The MBCN maintains an active node list.
